摘要
为实现复杂实体的自动装配,提出了一种在三维设计平台上实现自动装配的方法.该方法利用三维图形拓扑的边界表述对参与装配实体的图元进行标记,并存储到实体扩展数据当中,在装配中使用程序检索实体扩展数据获取相应的装配图元,然后以相应的装配关系把实体进行拼接,完成图形的自动装配.把该方法用于Inventor的二次开发中,取得了良好的效果.
A new method was proposed in order to realize automatic assembly for complex graphs on 3D design platform, which marked the graphic elements by BRep of 3D graphic topology and saved the data into the Xdata, then got the relevant elements by searching the Xdata in the process of assembly and jointed them according to assembly relationships to complete automatic assembly of graphs. It had achieved good results that the method was used in secondary development of Autodesk Inventor.
